Students from Machans Beach State School are helping to promote the connection between everyday actions and the health of the Great Barrier Reef through a Reef Guardians drain stencilling project.

Drains around the school grounds will be stencilled with the words 'This drains to the Great Barrier Reef' in an effort to reduce pollution flowing out to the Reef.

Great Barrier Reef Marine Park Authority Reef Guardian Schools Acting Program Manager Carolyn Luder said the stencilling project was a great opportunity to highlight the link between land-based pollution and the Reef.

"Today's activities will educate students and the school community about the connection between our everyday actions, and protecting the biodiversity of our environment and the Reef," Ms Luder said.

"The message on the drains reminds us all to act responsibly when disposing of rubbish and chemicals.

"Reducing the amount of pollution and debris in our drains significantly benefits the health of the Reef and the plants and animals that call it home."

Machans Beach State School is an active Reef Guardian School, encouraging understanding and awareness of the Reef and its connected ecosystems.

The stencilling project was made possible with the assistance of the Barron Delta Community Engagement Project and fellow Reef Guardians member, Cairns Regional Council.

"We would love to see more Reef Guardian Schools getting involved in activities to spread the word to communities about protecting stormwater drains from rubbish," Ms Luder said.

"As future custodians of the Reef, students are addressing the challenges facing the Reef, and the Reef Guardian program inspires them to make a positive difference."

Reef Guardian Schools are participating in many other environmental initiatives to improve waste, water and energy management and increase biodiversity.

This includes tree planting, recycling programs, and solar energy installations.

The Reef Guardian Schools program is an environmental education program run by the Great Barrier Reef Marine Park Authority.
